nfs, stale file handle

[Calle Kabo]

I've managed to install `nfs-kernel-server` and configured `/etc/exports`

/data/data1/Temp        *(rw,all_squash,insecure,async,no_subtree_check)

# showmount --exports
Export list for libreNAS:
/data/data1/Temp      *

# nfsstat -s

Server rpc stats:

However, when I try to mount the exported directory on my laptop I get this error

$ sudo mount -t nfs 172.22.22.20:/data/data1/Temp /mnt -o nfsvers=3 -vvv

^C

If I SSH into the GnuBee PC2 and run `ll /data/data1/Temp` I get a nice listing of the things in that directory, no problems.

What's going on??

GnuBee PC2, libreCMC v1.4.2

Maybe it's some sort of issue with btrfs?

mkdir /tmp/test
touch /tmp/test/t
# add /tmp/test to /etc/exports

Works fine mounting on my laptop.

Aha!

I needed to add fsid= to my exports options!

This whole thing only took about 12 hours more than it should have...
